Precious metal recycling_ Introduction to Rare and Precious Metal Ruthenium

The historical origin of ruthenium:

Ruthenium is a chemical element with the element symbol Ru and Atomic number 44. It is a rare silver white transition metal belonging to the platinum group element. It has long been known for its unique properties and applications. This Trace element is of great significance in many research and industrial fields. Its name comes from the Latin "ruthenus", which means "Russian". In 1844, German chemist Karl von Lychenbach discovered ruthenium for the first time. He found trace ruthenium in platinum ores collected in the Ural Mountains of Russia.

Application of Ruthenium: 1. Ruthenium is an extremely versatile element that has been used in many different applications in different industries. It has excellent mechanical strength, excellent corrosion resistance, and significant thermal stability. It also has high antioxidant properties and will not undergo embrittlement at higher temperatures. This makes it an excellent choice for components in high-temperature environments. Its conductivity is also very good, making it a useful material in electronic devices. Due to its low toxicity and non magnetism, it is also widely used in medical implants and pharmaceuticals.

2. In industrial applications, ruthenium is often used as a catalyst for chemical reactions. Due to its ability to withstand high temperatures, it is very useful in the refining process. It is also used as a reinforcing agent for alloys and as an additive for coatings, ceramics, and plastics.

3. In the automotive industry, ruthenium can be found in spark plugs, fuel injectors, and other components.

4. The unique properties of ruthenium have been explored in various scientific fields. For example, its ability to absorb and emit light makes it a popular choice in Spectroscopy, while its low reactivity and durability make it suitable for nuclear technology.

5. People are studying its catalytic ability for potential use in fuel cells, solar cells, and other renewable energy sources. In addition, ruthenium can be used as an electrode material for biosensors, helping to detect the presence of certain molecules in the environment.

Ruthenium can be obtained from natural resources such as platinum ore, but it is usually synthesized in the laboratory. Its compounds can form with other elements such as oxygen, chlorine, sulfur, and nitrogen, as well as organic molecules such as ammonia and acetylene. The synthesis process includes a series of steps, including oxidation, reduction, precipitation, and finally purification. Although ruthenium is not as rich as some other elements, it still plays an important role in many industries, and its versatile nature makes its application range very wide. With the advancement of technology and the increasing demand for ruthenium, the importance of ruthenium to the world will continue to increase.
